中文摘要：
为了揭示黄土高填方的沉降规律,并预测其工后沉降,对某高填方的监测成果进行分析,将FEM数值计算与分层迭代反演方法结合,对高填方的工后沉降进行反演预测。分析结果表明：填方体自身沉降占总沉降的63%而原地基沉降占37%,施工期产生沉降的主要原因是非饱和土孔隙气压密及排气固结,原地基和填方厚度的不均匀是地表差异沉降的主要原因。分层迭代反演法与FEM结合能更精确的反映施工加载对填土形变参数的影响,采用反演参数预测沉降值与现有实测数据吻合较好。
英文摘要：
In order to reveal the settlement behaviors of high filled embankment and to predict the post-construction settlement, the long-term in-situ monitoring data of a certain high filled loess embankment were analyzed with the FEM computation and the method of layered iteration to inversely predict the post-construction settlement. The results show that the settlement of the embankment itself is the main part of the total settlement and accounts for 63% of the total settlement, while the original ground settlement accounts for 37%. The construction settlement is mainly caused by the compression of the pore air and exhaust consolidation. The uneven foundation and different heights are the main reasons of differential surface settlement.
